Abstract: Arsenic is one of the naturally present and widely distributed toxicants in ecosystem. It is also produced by anthropogenic activities. As it is present in water bodies mainly, it can easily enter the food chain and finally reach human body. It has very severe carcinogenic and teratogenic effects on physiological systems. Current study focuses on the effect of arsenic on reproductive system. Our electron microscopic studies clearly demonstrate this effect. Nexin-dynein regulatory complex is a component of flagellum of the mammalian spermatozoa. It is mainly involved in regulating motility of spermatozoa......

Key words: Sodium Arsenite, Swiss Albino Mice, Spermatozoa, Nexin-Dynein

Abstract: Flood disasters, as a natural phenomenon related to human activities, occur as a result of the accumulation of several factors, such as rain, wind conditions, and upstream conditions. Natural conditions are also influenced indirectly by the increase in population, which can trigger flooding.This study aims to determine the level of knowledge and awareness of the community towards flood disasters and to examine the relationship between knowledge and community vigilance in facing flood disasters in Candikuning Village. The study uses a quantitative descriptive method with a bivariate correlation design and an ecological approach......

Key words: vigilance, flood disaster, Candikuning Village

Abstract: Background: The conversion of forest into perennial crops, particulary cocoa and rubber farms, is a phenomenon that is increasingly affecting protected areas in Ivory Coast. This situation reveal the contrast, which threatens the survival of biodiversity, this study examines the possibility of reconstituting these ecosystems from the floristic potential that is expressed in the cocoa and rubber farms. Materials and Methods: For this, 108 plots of 400 m2 each were first laid out in 54 selected cocoa farms and 54 selected rubber farms in the Indénié-Djuablin.....

Key words: Natural regeneration, Weeds, Cocoa and rubber farms.
